Hi I would like to control the margin in difference tier rather than standard margin % (0.5%, 1%). e.g. Stop loss = 2%, DJI close = 30,000 Fund = 1,000 Positionsize = 2 (tier 1) Positionsize = 60 (tier 2) margin = (close * 2/100) * positionsize Positionsize = Fund/(close * stop loss) I do not have idea..Who can help? thanks.
